The present invention will be clearer from the following descriptionwhen viewed together with the accompanying drawings, which show, forpurpose of illustrations only, the preferred embodiment in accordancewith the present invention.

Referring to FIGS. 1-2, an automatic pop-up cigar cutter in accordancewith a preferred embodiment of the present invention comprises a base10, a cutting blade assembly 20, at least one cutting blade spring 40, acontrol knob assembly 50, and a control spring 60.

The base 10 is formed at one side thereof with a cutting-blade-assemblyreceiving groove 11, and an assembling hole 12 penetrating thecutting-blade-assembly receiving groove 11 is formed adjacent to anopening of the cutting-blade-assembly receiving groove 11. Thecutting-blade-assembly receiving groove 11 is provided on at least oneside thereof with an assembling groove 13. In the present embodiment,the cutting-blade-assembly receiving groove 11 is provided on both sidesthereof with an assembling groove 13. The base 10 is further formed witha cutting hole 14 penetrating the cutting-blade-assembly receivinggroove 11, and the cutting hole 14 is normally round.

The cutting blade assembly 20 is disposed in the cutting-blade-assemblyreceiving groove 11 from the opening of the cutting-blade-assemblyreceiving groove 11 of the base 10. The cutting blade assembly 20 isprovided with a cutting blade 30 at an end thereof which extends intothe cutting-blade-assembly receiving groove 11. The cutting bladeassembly 20 is further provided on at least one side thereof with anassembling pin 21 for cooperating with the assembling groove 13, and inthe present embodiment, the cutting blade assembly 20 is provided onboth sides thereof with an assembling pin 21. The cutting blade assembly20 is formed with a fixing hole 31, and a moving hole 32 extending fromthe fixing hole 31 in the sliding direction of the cutting blade 30. Awidth of the fixing hole 31 is greater than that of the moving hole 32in the sliding direction of the cutting blade 30. The fixing hole 31 andthe moving hole 32 both are through holes.

In the present embodiment, two cutting blade springs 40 are provided.The two cutting blade springs 40 are mounted on the assembling pins 21in the assembling grooves 13. A first end of each of the two cuttingblade springs 40 is pressed against the base 10, and a second end ofeach of the two cutting blade springs 40 is pressed against the cuttingblade assembly 20, so that the cutting blade assembly 20 and the cuttingblade 30 are normally elastically pressed toward the opening of thecutting-blade-assembly receiving groove 11.

The control knob assembly 50 includes a fixing knob 51 and a moving knob52. The fixing knob 511 is formed with a fixing cylinder 511, and thefixing cylinder 511 is formed with a through hole 512. The moving knob52 is formed with a moving cylinder 521, and the moving cylinder 521 isinteriorly formed with a threaded portion 522. The fixing knob 51 andthe moving knob 52 are mated with each other in the assembling hole 12of the base 10, and a threaded element 53 is inserted through thethrough hole 512 of the fixing cylinder 511 and screwed with thethreaded portion 522 in such a manner that the fixing knob 51 and themoving knob 52 is located at both sides of the base 10. A sealing cover54 covers the through hole 512 of the fixing knob 51 to seal thethreaded element 53 in the through hole 512 of the fixing knob 51. Thewidth of the fixing cylinder 511 is smaller than that of the fixing hole31 and greater than that of the moving hole 32, and the width of themoving cylinder 521 is smaller than that of the moving hole 32, so thatthe fixing cylinder 511 and the moving cylinder 521 can move in theassembling hole 12 along a direction of the cutting blade 30. When thefixing cylinder 511 extends into the fixing hole 31, the cutting blade30 will be in a pressed stored state, and when the moving cylinder 521extends into the moving hole 32, the cutting blade 30 will be in apop-up state.

The control spring 60 is disposed between the moving knob 52 of thecontrol knob assembly 50 and the base 10. A first end of the controlspring 60 is pressed against the moving knob 52, and a second end of thecontrol spring 60 is pressed against the base 10. The control knobassembly 50 is normally elastically pressed toward the moving knob 52.

When the cigar cutter is not in use, as shown in FIGS. 3-4, pressing thecutting blade assembly 20 can push the cutting blade 30 downwardsthrough the cutting hole 14 and finally into the cutting-blade-assemblyreceiving groove 11, meanwhile, the cutting blade springs 40 will becompressed, and the fixing hole 31 of the cutting blade 30 will bealigned with the control knob assembly 50. Since the control spring 60elastically pushes against the moving knob 52, the moving knob 52 willprotrude outwards to push the fixing cylinder 511 of the fixing knob 51back into the fixing hole 31, and since the fixing cylinder 511 isbigger than the moving hole 32, the fixing cylinder 511 will be limitedin the fixing hole 31, thus keeping the cutting assembly 20 and thecutting blade 30 in the pressed state while keeping the cutting bladesprings 40 in a compressed state.

To use cigar cutter, as shown in FIGS. 5 and 6, pressing the moving knob52 of the control knob assembly 50 can push the fixing cylinder 511 awayfrom the fixing hole 31 while pressing the control spring 60 to make themoving cylinder 521 extend into the fixing hole 31 of the cutting blade30, since the moving cylinder 521 is smaller than the fixing hole 31 andthe moving hole 32, the compressed cutting blade springs 40 will pushthe cutting blade 30 out of the cutting-blade-assembly receiving groove11 and the moving hole 32 to move relative to the moving cylinder 521.When the moving cylinder 321 arrives at a second end of the moving hole32 from the fixing hole 31 at a first end of the moving hole 32, thecutting blade 30 will move away from the cutting hole 14, at thismoment, a cigar can be inserted into the cutting hole 14, and then thecutting assembly 20 will be pressed to move toward the cutting hole 14together with the cutting blade 30, and thus the cutting blade 30 willcut off the cigar in the cutting hole 14.

A cutting blade assembly 20A in accordance with another embodiment ofthe present invention, as shown in FIG. 7, includes a fixing hole 31 Awhich is a blind hole, and a moving hole 32A which is a through hole.
